Composing the message type string requires knowing the protocol discriminator.
To ease printing the message type, add this function to switch between the
defined value_string[]s depending on pdisc.
Also publish the message type value_string[]s -- without inline functions to
access them because it is anyway more convenient to use
gsm48_pdisc_msgtype_name() instead.
Since gsm48_pdisc_msgtype_name() is nontrivial, do not add as inline function
-- in case the message type is not known, it needs a static string buffer.

I often want to log the protocol discriminator in the openbsc debug log. It's

To be able to use OSMO_VALUE_STRING() on a #defined constant, don't use
OSMO_STRINGIFY(): the second indirection resolves the #define to its value, so
for example
OSMO_VALUE_STRING(GSM48_PDISC_MM)
would resolve to
{ 0x05, "0x05" }
When using '#x' directly, this becomes the desired
{ 0x05, "GSM48_PDISC_MM" }
With enum values as we've used until now, this problem does not appear, because
enum values are not resolved by the preprocessor.
Keep OSMO_STRINGIFY() because it is used directly in openbsc (composing FSM
state names).

Don't use CTRL_TYPE_UNKNOWN as value_string[] terminator, use an explicit, more
obvious { 0, NULL } termination. Set an explicit string for CTRL_TYPE_UNKNOWN.
No other value_string[]s to date have such a "hidden" terminator.
BTW, a { 0, "string" } item is not a terminator, only { 0, NULL } is, so we can
set a string for CTRL_TYPE_UNKNOWN == 0.
Also, having a string value for CTRL_TYPE_UNKNOWN is not harmful because all
code paths explicitly check for the CTRL_TYPE_*s that are valid.
Adjust the test expectation.
From the ctrl_type_vals enum, remove the = 0, because it is implicitly 0
anyway.
One motivation to press this fixup: I am trying to add a script that checks
whether all value_string[]s are terminated to our jenkins jobs, and to find
that this one is terminated, it would need to interpret the CTRL_TYPE_UNKNOWN
constant, which would make things far more complex. At this point, all of the
value_string[]s have an explicit termination, and I would like to enforce this
from now on -- for readable code and to not spend more time on the validator.
The patch adding ctrl_type_vals (Icd4e96dd9f00876cb70b43cfcf42ab4f10311b28) was
accepted by another reviewer before I could reconfirm my -1, so this is a fixup
to enable the termination checking script patches.

So far we incremented SQN by 1, which doesn't match the procedures described in
3GPP TS 33.102. An IND (index) denotes a non-significant part of SQN, and the
significant SEQ part needs to be incremented.
In OsmoHLR we furthermore want to use the "exception" suggested in annex C.3.4,
so that each HLR's client has a fixed IND index. In other words, we will not
assign IND cyclically, but keep IND unchanged per auth vector consumer.
Add 'ind_bitlen' and 'ind' to the osmo_sub_auth_data.u.umts structure and
increment SQN accordingly.
Add a comment explaining the details.
Because 'ind_bitlen' is still passed as zero, the milenage_test does not change
its behavior, which is a feature I want to clearly show in this patch. The test
will be expanded for the newly implemented SQN scheme in a subsequent patch.
Adjust osmo-auc-gen.c to still show the right SQN and SQN.MS -- because it is
passing ind_bitlen == 0, osmo-auc-gen can rely on single increments and know
SQN.MS is sqn - 1. Note that osmo-auc-gen_test output remains unchanged.

The previous version of this commit got reverted to avoid a breakage in openbsc.
The problem is openbsc use an array of chreq_type with a manual defined size. This array
is using enums as index which breaks if any elements got added into the
middle, because the size of the array can't hold elements greater or
equal than the size.

There are some projects, such as GR-GSM and OsmocomBB, which would
benefit from using one shared implementation of GSM 05.03 code. So,
this commit introduces a new sub-library called libosmocoding, which
(for now) provides GSM, GPRS and EDGE transcoding routines, migrated
from OsmoBTS.
The original GSM 05.03 code from OsmoBTS was relicensed under
GPLv2-or-later with permission of copyright holders (Andreas Eversberg,
Alexander Chemeris and Tom Tsou).
The following data types are currently supported:
- xCCH
- PDTCH (CS 1-4 and MCS 1-9)
- TCH/FR
- TCH/HR
- TCH/AFS
- RCH/AHS
- RACH

Commit 812ba6dc63
"logging: centrally define ctx and filter indexes"
Removed definitions, which causes older e.g. openbsc and osmo-pcu code trees to
fail to build against a newer libosmocore. Re-introduce the legacy definitions
to redirect to the new ones and re-establish backwards compatibility.
The GPRS_* constants used to be defined in gprs_msgb.h, but since that header
also includes logging.h, rather place the legacy shims in logging.h next to the
other ones.

MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE
of SI3.
Assuming that no-one is using the spare bits, this will not cause any code
conflicts.
In the R99 struct, spare1 and spare2 are in different places, so rather rename
them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone
tries to use them with the wrong structure.
Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by
TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section
10.5.2.11, so drop the explicit reference.
Motivation: the R99 Control Channel Description defines MSCR to indicate
whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to
indicate that our libmsc is capable of R99, like OsmoSGSN already does.
CBQ3 is merely added for completeness, no particular use case in mind.

It is too easy for calling code to use the same filter and context indexes for
different filters and structs. For example, openbsc's IMSI filter and libgb's
GPRS_BVC filter both fall on index 1 even though there are plenty more indexes
to choose from. To alleviate this, have one central definition here, sort of
like ports.h does for VTY and CTRL port numbers.
Add static asserts to make sure the indexes fit in the available array and bit
mask space.
Calling code like openbsc.git and osmo-pcu need adjustments and/or should move
to using these enum values instead of their local definitions.
Taking this opportunity to also prepare for a split of struct gsm_subscriber in
openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter
index constants for both subscriber types.
Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its
use by (1 << LOGGING_FILTER_ALL).

milenage_gen_vec() has parameter ordering of (..., auts, rand_auts, rand).
osmo_auth_gen_vec_auts() has (..., rand_auts, auts, rand), but actually feeds
args in the same order, so that its rand_auts becomes auts, and its auts
becomes rand_auts.
Interestingly enough, API user osmo-gen-vec.c also adheres to this misordering
and in turn passes auts for osmo_auth_gen_vec_auts()'s rand_auts and vice
versa, so that it matches milenage_gen_vec().
So both the implementation (milenage_*) and the API user use the same ordering,
just osmo_auth_gen_vec_auts() and osmo_auth_impl{ .gen_vec_auts() } in-between
have the argument names swapped.
Any current user of this API would need to adhere to this swapping or will not
get successful AUTS resolution to a SQN. So the least impact fix is to rename
the args without any actual functional change.
So swap the names rand_auts and auts for osmo_auth_gen_vec_auts() and
osmo_auth_impl{ .gen_vec_auts() }. (Also adjust API doc ordering)
Change-Id: I0dcbd49759fc32d3b8974102dbd1d6703364ebf4
GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same
procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS
to our osmo_auth_gen_vec_auts() API.
According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14
bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2
and AUTS being the V = 14.
It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But
writing 16 bytes to a GSUP struct is a potential problem when passing in a 14
byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer.
The API implies the length, so far to be 16, so passing in a 14 byte buffer to
GSUP would require copying to a larger buffer first.
Fix this by using a length of 14 for AUTS everywhere instead.
This constitues an ABI breakage, we may handle it as a "fix before an official
release", otherwise we need a version bump.
The OAP protocol document has also been updated, needs an update in the
osmo-gsm-manuals as well.

After subchan_demux.c in libosmo-abis, osmo-bts/common/vty.c and openbsc's
gtphub_test.c, more places would like to count the llist items (mostly unit
tests). Instead of proliferating numerous local implementations, add here.
NOTE: other than the previous llist_len() implementations, this one returns an
*unsigned* length, which might need some adjusting of current callers.
Call this llist_count() rather than llist_len() to highlight the fact that this
is actively iterating. This also avoids a potential naming conflict when
library versions mismatch.

osmo_fsm_inst_term() has code for safe child removal, publish that part as

As with osmo_fsm_inst_term(), add osmo_fsm_inst_term_children() macro to pass

Rationale: in openbsc's VLR, I want to discard child FSMs when certain events
are handled. I could keep a pointer to each one, or simply iterate all
children, making the code a lot simpler in some places.
(Unfortunately, the patch may be displayed subobtimally. This really only moves
the children-loop to a new function, replaces it with a call to
_osmo_fsm_inst_term_children(fi, OSMO_FSM_TERM_PARENT, NULL, file, line) and
drops two local iterator variables. No other code changes are made, even though
the diff may show large removal + addition chunks)
